STAY CLEAN WITH SOUND

Over 30 years of acoustic cleaning for various industries

Nirafon Oy provides customized acoustic cleaning systems for industries around the world. The company has over 30 years of experience in keeping processes clean in various types of applications, from boilers to channels, heat exchangers, silos, and much more.

The most energy-efficient cleaning solution

Nirafon acoustic cleaning systems provide the most energy-efficient solution for cleaning of powder-type impurities like ash, soot and cinder. This is thanks to their lower use of compressed air and continuous operation to keep the process efficiency high. The energy savings are considerable especially for power plants.

No water, no erosion, corrosion or mechanical wear

Nirafon systems drastically reduce the use of water at power plants. Steam is no more needed for soot blowing, so it can be used for its original purpose in power production.
Nirafon Oy is a part of Cleantech Finland, a hub of Finnish cleantech expertize and sustainable innovations.

Customized solutions for optimized results

Nirafon acoustic cleaning system is a combination of sonic horns, selected for each application separately. The system removes particles from the surfaces by acoustic pressure shocks. The pressure shocks are repeated until the required result for the cleaning have been achieved.

Cleanness maintained constantly

The system includes automatic control equipment that optimizes the cleaning results. The desired level of cleanness is constantly maintained by cleaning during ongoing process so that the process can continue smoother and efficiently without any interruptions.

Bringing substantial cost savings

Hundreds of plants already benefit from their Nirafon acoustic cleaning systems. The cost savings are a result of improved operating efficiency, increased production, reduced shut-downs and lower operating and maintenance costs.

PRODUCTS

NCSD® – SUPERIOR ACOUSTIC CLEANER

Nirafon Cleaning Sound Device (NCSD®) is an innovation typically used for the acoustic cleaning of the high temperature areas of boiler plants. NCSD® is the only solution on the market to keep the heat transfer surfaces clean even at spots where ashes are in both molten and solid forms.

NIRAFON PNEUMATIC ACOUSTIC CLEANERS

The Nirafon pneumatic/air-driven acoustic cleaners are typically used for the cleaning of lower temperature areas in different applications. Together with the NCSD®, these cleaners form the basis for our acoustic cleaning system engineering.

APPLICATIONS

CUSTOMISED SOLUTIONS FOR VARIOUS APPLICATIONS

Nirafon acoustic cleaning systems can be used in numerous applications, from waste-to-energy plants and incineration plants to recovery boilers or desulphurization plants – and much more. They are also an excellent choice for the cleaning of emission reduction technologies whose usage has lately increased due to tightening legislation, as is the case with Selective Catalytic Reduction (SCR) systems.
